Liam George Rush (born 29 January 1982) is an Australian former professional basketball player who spent the majority of his 15-year career playing in the Australian National Basketball League and Swedish Basketligan. In Sweden, he helped Sundsvall Dragons win championships in 2009 and 2011.

Rush was born in Broome, Western Australia.

Rush debuted in the State Basketball League (SBL) in 2000. He played for the Lakeside Lightning in 2000 and 2001, and then played for the Cockburn Cougars in 2002 and 2003. He played a third season with the Cougars in 2004.^{[citation needed]}

Rush started his professional career in 2003 with the Perth Wildcats of the National Basketball League (NBL). He played 19 games for the Wildcats during his rookie season in 2003/04, averaging 3.4 points per game. He went on to average 5.3 points in 2004/05 and 5.8 points in 2005/06. Following the 2005/06 NBL season, Rush had a stint in the SBL with the Willetton Tigers.

In 2006, Rush joined the West Sydney Razorbacks. In February 2007, Rush was named the recipient of the NBL Most Improved Player Award. Rush's regular season scoring average increased from 6.0 points per game in 2005/06 to 14.7 in 2006/07, while his rebounds doubled from 2.9 per game in 2005/06 to 5.6 per game in 2006/07. Rush also improved his scoring accuracy from 42% to 58% from the field, and from 28% to 47% from the three-point line. He was ranked fourth in the league from long distance during the regular season.

In 2007/08, Rush averaged 13.4 points, 5.5 rebounds, 2.7 assists and 1.4 steals in 29 games. Following the 2007/08 NBL season, Rush had a stint in the SBL with the Lakeside Lightning.

In 2008, the Razorbacks changed their name to the Sydney Spirit in a bid to broaden their supporter base after the collapse of the Sydney Kings. However, with reduced crowd numbers and a poor win–loss record, the Spirit reportedly faced million-dollar losses just two months into the season. As a result, Sydney Spirit owner Greg Evans placed the team into administration in late November 2008. Rush subsequently left the Spirit in early December after appearing in 15 games to begin the 2008/09 season.

On 12 December 2008, after exercising an out-clause in his contract with the Sydney Spirit, Rush signed with Swedish team Sundsvall Dragons for the rest of the 2008/09 Basketligan season. The Dragons had lost nine straight games and were second from the bottom when Rush arrived. His arrival sparked a turnaround that saw the Dragons claw their way to the top of the ladder and make the final play-off series. A victory over Solna Vikings, the reigning champions, was enough to bring the title to Sundsvall for the first time. Rush was the top scorer in the final game with 23 points.
